CAR BRAKE AND STARTER.

SPECIFICATION forming part of Letters Patent No. 230,506, dated July 27,1880. Application filed 11110 7.1880. (No model.)

To all whom it may concern:

Be it known that I, JAMES H. H. TAYLOR, of Lawrence, in the county ofEssex and State of Massachusetts, have invented a new and ImprovedMechanism for Stopping and Starting Street-(Jars, of which the followingis a specification.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 is aplan view. Fig. 3 is a side elevation of the gearing, the ratchet wheelbeing removed. elevation taken through the line .00 a,-Fig. 1. p Theobject of this invention is to furnish a mechanism for stopping andstarting streetcars, so constructed that the momentum of the car can beused for stopping the car, stored up, and again used for starting thecar, and which shall be simple in construction and convenient in use.

The invention consists in constructing a mechanism for stopping andstarting streetcars of a brake, a sleeve having brake-wheel.

and flange, a sleeve having internally-toothed gear-wheel,thegear-wheels connected with the inner sleeve and the axle, the rope,drum, and coiled spring, the pawl having arm and pins, theratchet-wheel, and the spring, whereby the forward movement of the caris made to coil a spring and stop the car, and the uncoiling of thespring is made to start the car, as set forth.

A represents the frame of a cart B represents an axle, which is designedto be connected with the frame Aand be provided with wheels in theordinary manner. Upon the axle B is placed a sleeve, 0, to one end ofwhich is attached a brake'wheel, D. Around the brake-wheel D are passedtwo or three coils of a rope, E, one end of which is attached to a barof the frame A, and its other end is attached to a lever, F. One end ofthe lever F is pivoted to the frame A, and its other end projects intosuch a position thatit may be conveniently reached and operated by thedriver.

With this construction, when the car is moving the sleeve 0 runs free,but when the lever F is operated the sleeve 0 will be held stationary.

I have described the sleeve 0 as being held by a rope and lever; but anyother convenient kind of brake may be used for that purpose. Upon theother end of the sleeve 0 is formed Fig. 4 is a sectional.

is turned by the gear-wheels H I J the rope a ring-flange, G, to whichare pivoted three gear-wheels, H, equal in size and at points equallydistant from each other. The teeth of the three gear-wheels H mesh intothe teeth of the gear-wheel I, keyed to or otherwise rigidly connectedwith the axle B. The teeth of the three gear-wheels H also mesh into theteeth of the internally-toothed gear-wheel J, attached to or formed uponthe end of the sleeve K. placed upon the sleeve 0. The sleeve 0 is keptfrom longitudinal movement upon the shaft B by the gear-wheel l and bythe collar L, secured to the said shaft B by a setscrew or othersuitable means. The sleeve K is kept from longitudinal movement upon thesleeve 0 by the flange G and the brake-wheel D.

With this construction, when the car is moving and the sleeve G is heldstationary the gear-wheels H I J cause the sleeve K to re 'volve, andwhen the sleeve K is held stationary the said gear-wheels cause thesleeve 0 to revolve. I To the sleeve K is attached the end of a rope, M,which is wound upon and has its other end attached to a drum, N,attached to the shaft 0. The shaft 0 revolves in bearin gs attached tothe frame A, and around it is coiled a spring, P, one end of which isattached to the shaft 0 and its other end is attached to the frame A.The spring P is so arranged that it will be coiled by the unwinding ofthe rope M, and by its uncoiling it will wind up the said rope M.

With this construction, when the sleeve K 8 M will be Wound upon thesleeve K and the 5 spring 1 will be coiled by the momentum of the car,the sleeve K turning in the opposite direction from the axle B. When thesleeve 0 isreleased the tension of the spring P will turn the sleeve Kin the opposite direction, or in the same direction as the axle B.

7 To a flange or other support formed upon or attached to the rim of theinternally-toothed gear-wheel J is pivoted a pawl, Q, which engages withthe teeth of a ratchet-wheel, R, keyed or otherwise secured to the axleB, so that the power of the spring P will be exerted upon the axle B insuch a direction as will turn the said axle B forward and start the car.Upon thepaw'l Qis formed, or to it is attached, an arm, S, whichprojects along the side of the ratchet-wheel R, and has two pins, T,attached to it at diflerent distances from its ends, and in suchpositions as to receive the spring U between them.

The spring U is made with a fork, which rides in a ring-groove in thehub of the ratchet-wheel R, and has so much friction that the forcerequired to move it upon the hub of the ratchet-wheel R will besuflicient to raise the engaging end of the pawl Q, away from the teethof the said ratchet-wheel R.

With this construction, when the sleeve 0 is free, and the sleeve K isheld from turning by the rope M and spring 1?, the pawl Q, S T, beingstationary, will hold the spring U from turning with the ratchet R, andthe friction of spring U in its groove will hold the engaging end of thepawl Q away from the teeth of the ratchetwheel R, and will thus preventnoise from the said pawl sliding over the ratchetteeth.

When the sleeve K and wheel J are turned forward by the action of thespring P the pressure of the pins T against the spring U will turn theengaging end of the pawl Q into contact with the teeth of theratchet-wheel B, so that the power of the spring P will be exerted uponthe axle B in the direction to turn the said axle and its wheels forwardand thus start the car.

With this construction the horses will be saved from the labor ofstarting the car, and will thus be able to draw the load with greaterease and rapidity than is possible when the car has to be started solelyby the power of the horses.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A mechanism for starting and stopping street-cars, constructedsubstantially as herein shown and described, consistin gof a brake, E F,the sleeve 0, having brake-wheel D and flange G, the sleeve K,havin ginternally-toothed gear- Wheel J, the gear-wheels H I, the rope, drum,and spring M N P, the pawlQ, S T, the ratchetwheel R, and the spring U,as set forth.

2. In a mechanism for stopping and starting street-cars, thecombination,with the frame A and axle B, of a brake, E F, the sleeveO,having brake-wheel D and flange G, the sleeve K, having internally-toothed gear-wheel J, the gear-wheels H I, the rope, drum, and spring MN P, the pawl Q, and theratchet-wheel R,substantially as herein shownand described, whereby the momentum of the car is used for stopping itand is then applied to the car for starting it, as set forth.

3. In a mechanism for stopping and starting street-cars, thecombination, with the axle B, the sleeves O K, and the ratchet-wheel R,of the gear-wheels H I J and the pawl Q, substantially as herein shownand described, whereby the forward movement of the axle will turn thesleeveKto coil a spring and the forward movement of the sleeve K willturn ratchet-wheel It by the movements of the gearwheel J, as set forth.
